Embodiment Construction

[0027] Attached below figure 1 , attached figure 2 The present invention will be further described in detail with specific embodiments.

[0028] Such as figure 1 As shown, the present invention provides a single-pile foundation for offshore wind power, which belongs to the single-pile foundation and is suitable for near-shallow sea areas.

[0029] The wind power host 1 and the wind power tower 2 are successively installed on the root-shaped pile foundation 3 .

[0030] The pile foundation 3 passes through the sea level and is installed on the seabed.

[0031] The tree root-like structure includes several roots, and each root is a tapered structure, wherein the width of the roots near the bottom of the monopile foundation body 3 is greater than the width of the roots away from the bottom of the monopile foundation body 3 .

[0032] Wherein, the root crown structure 4 at the bottom of the pile foundation 3 firmly "grasps" the soil on the seabed. Compared with the traditio...

Abstract

The invention provides a single-pile foundation for offshore wind power and a construction method thereof. The single-pile foundation comprises a single-pile foundation body, and the bottom of the single-pile foundation body is of a tree-root-shaped structure; the structure can meet the requirements of safety and stability without increasing the depth of the pile foundation; and the problems that the construction cost and the construction difficulty are obviously increased due to continuous increase of the depth of the offshore wind power single-pile foundation in the future are solved.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to a single pile foundation for offshore wind power and a construction method thereof. Background technique [0002] As a clean and harmless renewable energy, wind energy has been paid more and more attention by human beings. Among them, compared with land wind energy, offshore wind energy resources not only have higher wind speeds, but also are farther away from the coastline, and are not affected by noise limits, allowing larger unit manufacturing. [0003] The pile foundation of offshore wind power is very different from that of onshore wind power, mainly in the pile foundation. Since offshore wind turbine equipment will be impacted by waves and ocean currents during operation, a stronger pile foundation is required. Generally, the wind power foundation in the shallow sea area is a fixed pile foundation, that is, the pile foundation is fixed on the seabed in a straight-line ma...
